Gene therapy helps sightless people
There are two types of photoreceptors in the omentum, one is cone cells and the other is rod cells. Opsin is distributed on the surface of photoreceptor cells ...
Opsin in rod cells is rhodopsin, and opsin in cones is cones.
In the past, cataracts did not consider surgery until they matured. This is due to technical limitations in the past, but now medical technology and equipment are constantly updated, and surgery does not need to wait until the cataracts are fully mature. At present, cold phacoemulsification and intraocular lens implantation are used. The surgical wound has an ultra-small incision, which greatly improves the safety and effectiveness of the operation. Conversely, waiting until cataracts are too 'mature' can have serious consequences. First, it is very easy to induce secondary glaucoma, causing vision loss, and it will be more difficult to treat. Second, lens material is released into the eye, which induces an allergic reaction, which leads to lens allergic uveitis, which not only affects the treatment of the affected eye , May also affect another good eye. Cataract patients with vision below 0.5 can go to the hospital for detailed preoperative examinations and consider surgery as appropriate.Read More
